Octave's appearance at Rossini's opera is the last he ever puts in at any theater; in fact, he had intended it to be the last appearance he ever made in society before setting off Byronically
to fight against the Turks in the cause of Greek independence.
Perhaps the Byronically
contrarian Cain, creation's first nostalgic firstborn son who grudges a life of toil "because / My father could not keep his place in Eden" and loiters around its closed gates at twilight "to catch a glimpse of those / Gardens which are my just inheritance" (CPW VI: 234-35), is Byron's best oblique embodiment of his British aristocratic land-leaving regret.
In his final fragment, the apocalypse, once sweet in Shelley's mouth, is Byronically
bitter in his now "excrementitious" belly.
